Only a handful of specialized non-conifer species of vegetation are able to survive the wet conditions of the Northern Forest. Flowering plants (Angiosperms) are rare in this lush forest. They have been replaced primarily by another highly versatile organism: lichen. Slithersuckers have a symbiotic relationship with lichen trees in that nutrients from a slithersucker's meal will nourish the tree itself. Lichen trees grow diamond-shaped fruit which is favored by many animals of the forest, such as megasquids and squibbons.
